Paraesophageal hernias (PEH) account for approximately 5% of all hiatal hernias and involve herniation of the stomach (and sometimes other abdominal organs) through the diaphragmatic hiatus alongside the esophagus. [1] They are classified as Type II (true paraesophageal, GEJ in normal position), Type III (mixed, most common PEH type), and Type IV (additional organs herniated). [1] While often incidentally discovered, PEH can present as a true surgical emergency with incarceration, volvulus, strangulation, or perforation. [1]
1. History
- Key HPI questions: Onset, duration, and character of chest/epigastric pain; relationship to meals (postprandial distress is the most prominent symptom in Type III PEH); ability to tolerate oral intake; emesis (especially inability to vomit — Borchardt's triad) [2]
- Symptom characterization: Heartburn (65%), early satiety (50%), chest pain (48%), dyspnea (48%), dysphagia (48%), regurgitation (47%); median number of symptoms is 4 per patient [3]
- Timing/triggers: Postprandial bloating, pain during or shortly after meals, worsening with large meals or recumbency [2]
- Associated symptoms: Chronic cough, aspiration pneumonia, iron-deficiency anemia (41% of patients, from Cameron ulcers/gastric erosions) [1][3]
- Important negatives: Absence of hematemesis, melena, weight loss, fever; ability to pass flatus
2. Alarm Features
- Borchardt's triad (classic for gastric volvulus): severe epigastric pain, retching without vomiting, inability to pass NGT — suggests incarcerated/volvulized stomach
- Acute chest pain with hemodynamic instability — consider strangulation or perforation
- Signs of sepsis, peritonitis, or respiratory failure [4]
- Acute gastric ischemia/necrosis carries mortality ≥30% depending on delay to intervention [1]
- Emergent repair mortality is approximately 6.7% vs <1% for elective repair [5]
3. Medications
- Acute management: PPIs for reflux symptom control; antiemetics for nausea/vomiting
- Avoid: NSAIDs (exacerbate Cameron ulcers and gastric erosions contributing to anemia)
- Iron supplementation for chronic iron-deficiency anemia secondary to Cameron ulcers
- Post-surgical: PPI therapy typically continued postoperatively; stool softeners to avoid straining
- Caution: Anticholinergics and opioids may worsen gastric dysmotility and obstruction
4. Diet
- Acute presentation: NPO if obstruction, volvulus, or surgical intervention anticipated
- Chronic/outpatient management: Small, frequent meals; avoid large-volume meals that worsen postprandial distress and early satiety [2]
- Avoid eating within 2–3 hours of recumbency
- Minimize carbonated beverages, fatty foods, and known GERD triggers
- Elevate head of bed for nocturnal reflux symptoms
5. Review of Systems
- GI: Dysphagia, odynophagia, nausea, vomiting, hematemesis, melena, early satiety, bloating, heartburn, regurgitation
- Pulmonary: Dyspnea (especially postprandial — from mechanical compression or aspiration), chronic cough, recurrent pneumonia [3]
- Cardiac: Chest pain (must differentiate from ACS)
- Constitutional: Fatigue, exercise intolerance (anemia), unintentional weight loss
- Hematologic: Symptoms of anemia — pallor, lightheadedness
6. Collateral History and Family History
- Prior imaging showing hiatal hernia or incidental findings on CXR/CT
- History of prior foregut surgery (fundoplication is a risk factor for acquired PEH, especially in pediatric populations) [6]
- Connective tissue disorders (Ehlers-Danlos, Marfan) — associated with diaphragmatic laxity
- Family history of hiatal hernias or connective tissue disease
- Functional status and surgical candidacy in elderly patients
7. Risk Factors
- Age — most patients are elderly (median age ~64–70 years) [3][7]
- Female sex — 63–82% of surgical PEH cohorts are female [3][7]
- Obesity/abdominal adiposity — increased waist-hip ratio and trunk fat are genetically associated with hiatal hernia (OR 2.57 and 3.53, respectively) [8]
- Heavy physical labor — independent risk factor [8]
- GERD — independent risk factor for hiatal hernia development [8]
- Smoking — genetically associated with hiatal hernia [8]
- Prior esophageal/gastric surgery [6]
- Chronic increased intra-abdominal pressure (chronic cough, constipation, pregnancy)
8. Differential Diagnosis
- Acute coronary syndrome / myocardial infarction — PEH chest pain is easily mistaken for cardiac ischemia; maintain high index of suspicion [9]
- Acute pancreatitis — epigastric pain radiating to back
- Peptic ulcer disease / perforation — epigastric pain, peritonitis
- Esophageal perforation (Boerhaave syndrome) — chest pain, vomiting, subcutaneous emphysema
- Small bowel obstruction — vomiting, distension, obstipation
- Pulmonary embolism — dyspnea, chest pain, tachycardia
- Tension pneumothorax — if CXR shows lucency in hemithorax
- Pericarditis / pericardial effusion — chest pain, positional component
- Diaphragmatic rupture (traumatic) — similar imaging findings [10]
9. Past Medical History
- Prior hiatal hernia or PEH diagnosis
- Previous fundoplication or other foregut surgery (risk for recurrent/acquired PEH)
- GERD history and medication use
- Chronic anemia workup history
- Cardiopulmonary comorbidities — critical for surgical risk stratification (heart disease and diabetes predict worse outcomes with nonelective repair) [5]
10. Physical Exam
- Vital signs: Tachycardia, hypotension (suggest strangulation/perforation/sepsis); tachypnea, hypoxia (mechanical compression or aspiration)
- Chest: Decreased breath sounds at left base; bowel sounds auscultated in chest (pathognomonic but uncommon)
- Abdomen: Epigastric tenderness, distension; peritoneal signs (guarding, rigidity) suggest perforation
- General: Pallor (chronic anemia), signs of dehydration
- Rectal exam: Guaiac testing for occult GI bleeding
11. Lab Studies
- CBC: Iron-deficiency anemia (microcytic) — present in up to 41% of PEH patients; leukocytosis if strangulation/perforation [3]
- BMP/CMP: Electrolyte derangements from vomiting/dehydration; BUN/Cr for renal function; elevated lactate if ischemia suspected
- Lactate: Elevated in gastric ischemia/strangulation
- Type and screen: If anemia is severe or surgical intervention anticipated
- Coagulation studies: Preoperative
- Troponin: To rule out ACS when chest pain is the presenting complaint
- Iron studies, reticulocyte count: For chronic anemia workup
12. Imaging
- Chest X-ray (first-line): Retrocardiac air-fluid level, gastric bubble in thorax, mediastinal shift; NGT coiling in chest is diagnostic. Sensitivity is limited (2–60%) but useful as initial screen [10]
- CT chest/abdomen with contrast (gold standard in the ED): Defines hernia type, size, contents; identifies volvulus, ischemia (absent wall enhancement, pneumatosis, portal venous gas), perforation [1][10]
- Barium esophagram: Best for elective anatomic characterization and differentiating PEH types from sliding hernias; superior to endoscopy for hernia classification [11]
- Imaging unnecessary: Stable, known PEH with unchanged chronic symptoms and no alarm features
13. Special Tests
- Upper endoscopy (EGD): Evaluates for Cameron ulcers, esophagitis, Barrett esophagus, ischemia; also therapeutic for gastric decompression in acute incarceration (used in 76% of urgent cases) [1][7]
- Esophageal manometry: Guides fundoplication type (partial vs. complete) based on peristaltic function; if not feasible, partial fundoplication is preferred [1]
- 24-hour pH monitoring: Generally not required preoperatively as fundoplication is performed regardless [1]
- Pulmonary function tests / cardiac risk assessment: Important in elderly patients for perioperative planning [1]
14. ECG
- Indications: All patients presenting with chest pain to rule out ACS
- Findings to recognize: ST changes from mechanical cardiac compression by a large intrathoracic stomach (can mimic inferior STEMI); pericardial irritation patterns
- Key pearl: Always consider PEH in the differential of "STEMI mimics" in elderly patients with chest pain and abnormal CXR
15. Assessment
Paraesophageal hernias exist on a spectrum from asymptomatic incidental findings to life-threatening surgical emergencies. Type III (mixed) is the most common PEH subtype. [1] The critical ED distinction is between:
- Uncomplicated PEH: Chronic reflux/obstructive symptoms — amenable to outpatient workup and elective repair
- Complicated PEH: Incarceration, gastric volvulus, strangulation, perforation — requires emergent intervention
Textbook outcomes (no complications, no reoperation, discharge home) are achieved in 88% of elective repairs vs. 58% urgent and 47% emergent. [5]
16. Treatment Plan
- Initial stabilization (acute presentation):
- IV access, fluid resuscitation, NPO
- NGT placement for gastric decompression (critical first step; converts emergent to semi-elective in most cases) [1][12]
- EGD for decompression and mucosal assessment if NGT fails or to evaluate for ischemia [1][7]
- IV PPI, antiemetics, pain management
- Broad-spectrum antibiotics if perforation/sepsis suspected
- Surgical repair:
- Elective laparoscopic/robotic repair is the standard for symptomatic PEH: hernia reduction, sac excision, crural closure ± mesh reinforcement, fundoplication ± gastropexy [1][13-14]
- Urgent repair during the same admission after decompression yields outcomes comparable to elective repair [7][12]
- Emergent open repair reserved for perforation, necrosis, or hemodynamic instability — mortality up to 6.7% [1][5]
- Mesh reinforcement reduces recurrence (3.9% vs. 66.7% suture-only); anterior gastropexy improves anatomical stability [13-14]
- Nissen fundoplication is the most common antireflux procedure (52% of cases) [7]
- Nonoperative management: Acceptable for asymptomatic or minimally symptomatic PEH, as the risk of strangulation is lower than operative morbidity in this population [1]
17. Disposition
- Admit (with surgical consultation):
- Acute incarceration, volvulus, obstruction, or inability to tolerate PO
- Signs of ischemia, perforation, or hemodynamic instability
- Significant anemia requiring transfusion
- Failed NGT decompression
- Observation:
- Discharge:
- Known PEH with chronic, stable symptoms and no alarm features
- Successful conservative management with ability to tolerate liquids and passage of contrast on UGI [12]
- Specialist consultation triggers: General/thoracic surgery for all acute presentations; GI for elective EGD and preoperative workup [15]
18. Follow Up / Return Precautions
- Follow-up timing: Surgical consultation within 1–2 weeks for symptomatic PEH; sooner if discharged after acute episode with planned interval repair
- Return immediately for: Inability to eat or drink, intractable vomiting, severe chest or abdominal pain, hematemesis, melena, fever, shortness of breath, lightheadedness/syncope
- Patient counseling: Small frequent meals, upright positioning after eating, avoid heavy lifting/straining; PEH can recur even after surgical repair (radiographic recurrence up to 15–59%, though many are asymptomatic) [1][16]
- Expected recovery (post-surgical): Median LOS 3–4 days for elective/urgent repair; diet advanced from liquids to soft foods over 4–6 weeks; symptom improvement in 67–93% across symptom categories [3][7]
